Heartbreak in space (5)
I believe the answer is:
earth
This might be a double definition.
'heartbreak in' is the first definition.
The definition and answer can be both substances as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'space' is the second definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for earth that I've seen before include "Soil; ground terminal" , "Make electrics safe" , "our present abode" , "Heart (anag)" , "It is necessary to clear" .)
